26
Short term memory is characterised by the following characteristics:

(3) quickly accessed.
27
Types of rehearsal
There are two types of rehearsal
maintenance rehearsal
| elaborative rehearsal
28
Types of rehearsal

Self Reference effect - improved recall of information we can relate to ourselves (semantic encoding)
elaborative
29
Types of rehearsal
_____ rehearsal involves the conscious repetition of information, either to maintain it in consciousness (STM) or to encode it for storage. The hour before bed is best but not the seconds before.
maintenance
- is useful for STM
30
Long-term Memory (LTM)

lifetime
31
Extracting information from the LTM is called
retrieval
32
A tendency to recall best the last (recency) and first items (primacy) in a a list.
Serial Position Curve
33

effects reflects ___
LTM, STM
34
Originally memory was conceptualised in terms of the _____ _____ Model. This model proposes that the stages of memory occur in a _____ order i.e. one at a time from sensory registers ->STM -> LTM. But we now know that ______ information is processes unconsciously, rather than consciously in the STM. Also, what information is deemed important enough to move from the sensory register to STM is influenced by LTM, this means that LTM may be _____ before STM rather than the other way round as indicated by the Serial Processing Model. Information is more likely to be deemed important if it relates to information already stored in _____.
Serial Processing, sequential, sensory, activated, LTM
35
Memory is no longer thought of in terms of a serial processing model but is now thought to be
comprised of a number of modules which are discrete but interdependent (parallel processing).
36
In line with a neuropsychological view of memory processing we now know that memory consists of
a series of interdependent modules each responsible for a different kind of processing of in-coming information and remembering
37
When we simultaneously hear thunder the sound is processed by our temporal lobe which processes auditory sound while the lightening is processed by our occipital and lower temporal lobes. This means that when we remember an event we remember it as ???
It as one experience that has in fact been processed simultaneously by different parts of our brain
38
Memory is no longer likened to the processing of a computer it is now ____ as ____
mind, brain.
39
working memory consists of two components:
(1) temporary storage (STM)
| (2) mental control.
40
Working memory is a newer understanding of short-term memory that involves conscious, active processing of incoming information and of information retrieved from long-term memory (hold 1 task at a time) or
the temporary storage and processing of information that can be used to solve problems, respond to environmental demands or achieve goals.
41
Unlike ____ which is seen as a single storage unit, _____ memory is viewed as having multiple _____ with the storage system and processing systems NOT _____ for space.
STM, working, systems, competing
42
Working Memory
Baddeley and Hitch (1974) proposed that memory consists of three memory systems:
(1) a visual memory store;
(2) a verbal memory store; and,
(3) a “central executive that controls and manipulates the information these two short-term stores hold in mind”
43
Working Memory
The _____ _____ controls the flow and processing of information (limited capacity) to and from the verbal phonological stores and visuospatial sketchpad.
Central executive
44
Working Memory
The visuospatial sketchpad (visual memory store)
is a temporary image (__-__ seconds) that stores information about the location and nature of objects
20–30
45
Working Memory
Verbal memory store (phonological loop)
Involves storage of verbal items (equates to STM). It has limited capacity.
46
Neuropsychology of Working Memory
Working memory is thought to be directed by the _____ cortex, _____ and _____ working memory activate different _____ regions of the brain. This demonstrates the independence of different components of working memory.
prefrontal, Verbal, visual, cortical
47
Working Memory and LTM
Evidence supports a distinction between working memory and LTM in that people can have severe deficits in working memory without LTM being affected and vice-versa.
However these components of memory are intertwined. Working memory draws on information stored in LTM. LTM activation occurs via working memory.
48
Working Memory and LTM
Using knowledge in the LTM organising items into familiar, manageable units; often occurs automaticallyr easier comprehension
Chunking - increase capacity of working memory

76
Long Term Memory - Memory that is for things from the past is known as:

meaning of the stimulus
81
Encoding is the process whereby information is
converted into representational form, which enables later retrieval.
82

83
Long-Term Memory
_____ processing, which involves focusing on the meaning of the words and sentence meaning as a whole

84
Long-Term Memory (LTM)
The ease of retrieval of a memory depends on a match between the way information was encoded and how it is later retrieved is a phenomenon known as the
Encoding Specificity Principle
85
Long-Term Memory
superficial details = shallow processing
meaningful information = deep processing
An extension of this view is that memory is simply a by-product of perceiving and thinking which lays down a neural pathway. When the reason for retrieval conforms with the original processing style the connections are easily activated.
86
Cues in the retrieval context match cues in the original encoding context thus facilitating retrieval.
Retrieval cues
87

93
These make encoding and retrieval easier because they connect new information with already stored information
Networks of association
94
_____ may be thoughts, images, concepts, propositions, smells, tastes, emotions or any other piece of information. Because one node can have connections to many other nodes, it can lead to tremendously complex associations.

97
Spreading activation
Activating one node in a network triggers activation in closely related nodes.
98
Patterns of thought , or organised knowledge structures, that render the environment relatively predictable are called
schemas
99
Efficient retrieval of information requires that nodes are organised in some logical way.
Hierarchical storage is one such way.
100
Schemas affect the way people remember in two ways:

102
‘Seven Sins of Memory’
```
Transience: memories _____ with time
Absent-mindedness: need to pay _____ to remember
Misattribution: source _____
Suggestibility: thinking we remember
Bias: _____ in recall
Persistence: recurring _____
Forgetting: inability to _____
```
fade, attention, amnesia, distortions, memories, remember
Many of Schacter’s “sins” stem from adaptive memory processes that go awry. For example, if memory were not transient or temporary, our minds would eventually overflow with irrelevant information.

107
Theories of Forgetting
This Interference theory conceptualised that there is conflict between new and old memories. Name the 2 ways this happens
Proactive
| Retroactive
108
Theories of Forgetting
______ interference - The disruptive effect of prior learning on the recall of new information(present forgotten)
proactive interference
- occurs when previously learned information is lost because it is mixed up with new and somewhat similar information
109
Theories of Forgetting
_______ interference - The disruptive effect of new learning on the recall of old information (past forgotten)

Ebbinghaus found the more time spent rehearsing a skill initially, the less time it takes to relearn the next day or later; in order for it to be stored in our long term memory, rehearsal after the skill is attained is essential.
Retention Curve
117
